Crash after Building Lights

I am on unreal engine 5.3.1, and everytime I finish building lights, the engine crashes giving the following error. Please Note: that it finishes encoding textures, finishes building reflection captures, and when build log window pops up it crashes. Please help, I am at the final stages of a project… My machine is top of the line

Greetings @Pheonix00

Welcome back to the Unreal Engine Forums! With the DirectX 12 errors showing up there I’d recommend trying it with DirectX 11 and see if it continues. If so, respond here and we can check some other areas. I hope this resolves it!

I cannot do that, my project specifically relies on Nanite, Virtual shadow maps, and Raytracing. Doing so basically means destroying the whole project. And I cannot switch to SM5 because SM6 is needed for virtual shadow maps. Is there anything else I can do?

What type of GPU do you currently use? If it’s NVIDIA I’d consider checking and ensuring that you have the latest drivers and perhaps even resetting your graphics presets in the NVIDIA Control Panel to global default.
